the problem is simple: distributions will NOT use it. They can't, they
need the newer HW support and the new features. The only difference is
that you basically added just another distro branch. If you knew how
many people it takes a distro to run such an old tree you'd be scared.
(you need to include the QA people as well in this)

And distros hardly add hw support (the only hw support the enterprise
distros add is contained to like 5 or 10 drivers of "enterprise" stuff,
well testable and often validated by the vendor of the hw; and even then
there are regressions regularly)... for your branch you target a
different audience that does want a lot broader new HW support.

And then there's the bugfixes.. those tend to have regressions too,
especially if you move them to a different context than they originally
came from.

I'm not saying that you couldn't or shouldn't do this, I'm just saying
that I think it'll be a LOT more work than you think, and that the gain
is relatively minor. Especially since the main branch needs to sort the
compatibility item ANYWAY.
